Safety instructions

Contents of this chapter

This chapter contains safety instructions which you must obey when you install and

operate the converter, and do maintenance on the converter. If you ignore the safety

instructions, injury, death or damage can occur to the converter, the generator or

other adjoining equipment. Read the safety instructions before you work on the unit.

Use of warnings and notes

There are two types of safety instructions throughout this manual: warnings and

notes. Warnings tell you about conditions which can cause injury or death, or

damage to the equipment. They also tell you how to prevent the danger. Notes draw

attention to a particular condition or fact, or give information on a subject. The

manual uses these warning symbols:

Electricity warning tells about hazards from electricity which can cause

injury or death, or damage to the equipment.

General warning tells about conditions, other than those caused by

electricity, which can cause injury or death, or damage to the equipment.

Electrostatic sensitive devices warning tells you about the risk of

electrostatic discharge which can cause damage to the equipment.

High temperature warning warns about hot surfaces. Some parts inside

the converter cabinet remain hot for a while after the disconnection of

main power.

Installation and maintenance work

These warnings are intended for all who work on the converter, generator cable or

generator.

WARNING!

•

Only qualified electricians are allowed to install and maintain the converter.

•

Before any installation work, the stator of the generator and the supply line

input of the ACS800-67 must be isolated from the supply grid. It is also highly

recommended that the rotor of the generator is locked with a mechanical brake.

•

The stator and the converter are not to be reconnected until the installation is

complete.

•

Never work on the converter, the generator cable or the generator when power

is applied. After switching off the input power, always wait for 5 min to let the

intermediate circuit capacitors discharge before you start working on the

converter, the generator or the generator cable. Measure the voltage between

terminals UDC+ and UDC- with a multimeter (impedance at least 1 Mohm) to

ensure that the converter is discharged before beginning work.

•

Before working in the converter power cabinet:

Stop the fan, generator and converter. Lock the fan shaft mechanically. Switch

off the main breaker, contactor of the stator circuit and the breaker of the fan

transformer.

Lock the main breaker of converter.

Because the main breaker of converter is non-extractable, the isolation fan

transformer switch needed to be isolated and locked in isolation position to

ensure the safety.

Ensure by measuring that the main circuit of the converter and incoming cable

have been discharged (it takes 10 minutes after the power switch off).

Temporary ground the main circuit.

•

Apply temporary grounding before working on the unit.

•

Do not work on the control cables when power is applied to the converter or to

the external control circuits. Externally supplied control circuits can cause

dangerous voltages to exist inside the converter even when the main power of

the converter is switched off.

•

Control boards of the converter unit can be at the main circuit potential.

Dangerous voltages can be present between the control boards and the frame

of the converter unit when the main circuit voltage is on. It is critical that the

measuring instruments, such as an oscilloscope, are used with caution and

safety always as a priority. The fault tracing instructions give special mention of

cases in which measurements may be performed on the control boards, also

indicating the measuring method to be used.

Safety instructions

•

Do not make any insulation tests without disconnecting the converter from the

cabling first.

•

When joining shipping splits (if any), check the cable connections at the joints

before switching on the supply voltage.

•

Live parts on the inside of the doors are protected against direct contact. Pay

special attention when handling metallic shrouds.

Note:

•

If the main circuit of the converter unit is live, the output terminals are also live

even if the converter stage is not modulating.

•

The brake control terminals (UDC+, UDC-, R+ and R- terminals) are at

dangerous DC voltage.

•

Depending on the external wiring, dangerous voltages (115 V, 220 V or 230 V)

can be present on the relay outputs of the converter system.

•

The Prevention of Unexpected Start function does not remove the voltage from

the main and auxiliary circuits.

Safety instructions

WARNING! Ignoring the following instructions can cause physical injury or death, or

damage to the equipment.

•

Use extreme caution when manoeuvring a converter or filter module that runs

on wheels. The modules are heavy and have a high center of gravity. Make

sure that the module does not topple over when you move it on the floor.

•

Beware of the cooling fan blades. The fans can continue to rotate for a while

after the disconnection of the electrical supply.

•

Beware of hot surfaces. Some parts inside the converter cabinet, such as

heatsinks of power semiconductors, remain hot for a while after the

disconnection of the electrical supply.

•

Make sure that dust from drilling does not enter the converter when installing.

Electrically conductive dust inside the unit may cause damage or lead to

malfunction.

Do not tilt!

Support bottom of module

Lift the module by the upper part only using

the lifting hole(s) at the top!

Extend the support legs of the converter

module outside the cabinet!

Grounding

These instructions are for all personnel who are responsible for the grounding of the

converter.

•

Fastening the cabinet by riveting or welding is not recommended. However, if

welding is necessary, ensure the return wire is properly connected in order not

to damage the electronic equipment in the cabinet. Also ensure that welding

fumes are not inhaled.

•

Ensure sufficient cooling of the unit.

WARNING! Ignoring the following instructions can cause damage to the equipment.

•

The printed circuit boards contain components sensitive to electrostatic

discharge. Wear a grounding wrist band when handling the boards. Do not

touch the boards unnecessarily.

WARNING! Ignoring the following instructions can cause physical injury or death,

or damage to the equipment.

•

Ground the converter, the generator and adjoining equipment to ensure

personnel safety in all circumstances, and to reduce electromagnetic emission

and pick-up.

•

Make sure that the conductivity of the grounding conductors is sufficient. Obey

the local regulations.

•

In a multiple-converter installation, connect each converter separately to

protective earth (PE).

•

Do not install a converter equipped with an EMC (line) filter to an ungrounded

power system or a high resistance-grounded (over 30 ohms) power system.

Note:

•

Power cable shields are suitable for equipment grounding conductors only

when adequately sized to meet safety regulations.

•

As the normal leakage current of the converter is higher than 3.5 mA AC or

10 mA DC, a fixed protective earth connection is required by EN 61800-5-1,

4.3.5.5.2. The cross-section of the protective grounding conductor must be at

least 10 mm

2

Cu or 16 mm

2

Al.

Fibre optic cables

Operation

These warnings are intended for all who plan the operation of the converter or

operate the converter. Ignoring the instructions can cause physical injury or death or

damage the equipment.

WARNING! Obey these instructions. If you ignore them, equipment malfunction

and damage to the fiber optic cables can occur.

•

Handle the fibre optic cables with care. When you unplug the cables, always

hold the connector, not the cable itself. Do not touch the ends of the fibers with

bare hands as the ends are extremely sensitive to dirt. Do not bend the fiber

optic cables too tightly. The minimum allowed bend radius is 35 mm (1.4 in).

WARNING! Ignoring the following instructions can cause physical injury or death,

or damage to the equipment.

•

Before adjusting the converter and putting it into service, ensure that the

generator and all adjoining equipment are suitable for operation throughout the

speed range provided by the converter.

•

Do not operate breakers, contactors, switches or other equipment inside the

cabinet when the power is applied. Electric shock may occur also in case of

faulty component.

•

Do not stand behind the converter when the power is applied. In the event of

possible arc inside the cabinet the arc fumes and pressure exit through the

backside filter.

•

Keep the converter doors locked when the converter is in operation.

Note:

•

When the control location is not set to Local (L not shown in the status row of

the display), the stop key on the control panel will not stop the converter. To

stop the converter using the control panel, press the LOC/REM key and then

the stop key .
